The on-orbit plume thermal protection device for the spacecraft side-wall-mounted engine comprises a protection cover body, a protection cover plate and a high-temperature heat insulation screen assembly. The protective cover body is installed on the side wall of a spacecraft through a fastener. The protective cover cover plate is mounted at the top of the protective cover body through a fastener, and a spacecraft engine jet pipe mounting hole is formed in the protective cover cover plate; the high-temperature heat shield assembly covers the outer surfaces of the protective cover body and the protective cover cover plate to form a closed barrier layer, and is connected with the protective cover body and the protective cover cover plate through fasteners. The requirement for on-orbit plume thermal protection of a spacecraft with an engine installed on the side wall is met.

    本发明的航天器侧壁安装发动机在轨羽流热防护装置包括防护罩本体、防护罩盖板和高温隔热屏组件;所述防护罩本体通过紧固件安装在航天器侧壁上;所述防护罩盖板通过紧固件安装在所述防护罩本体的顶部,所述防护罩盖板设有航天器发动机喷管安装孔;所述高温隔热屏组件覆盖在所述防护罩本体和所述防护罩盖板的外表面上,形成一封闭阻隔层,并通过紧固件与所述防护罩本体和所述防护罩盖板连接。本发明满足侧壁安装发动机的航天器在轨羽流热防护的需求。
